thanksgiving sacrifice (NRSV) /thank offering (REB)

An animal sacrifice offered in gratitude for some favour received; the meat was shared between the donor and the priest, who had laid his hand
on the victim's head. They ate round the altar at a kind of communion meal (hence NJB ‘communion sacrifice’ at Lev. 7: 13) which included unleavened cakes (Lev. 7: 12). In Judaism a thanksgiving (berakah) was offered at meals, and Jesus followed this practice at the Lord's Supper. He gave thanks (Greek, eucharistesas, 1 Cor. 11: 24), which became a technical term by the 2nd cent. for the Breaking of Bread.
